Johns Hopkins team examines Kepler’s supernova using NASA’s three Great Observatories
On the night of October 9, 1604, sky watchers – including Johannes Kepler, an astronomer best known for discovering the laws of planetary motion – were startled by the sudden appearance in the western sky of a "new star" which rivaled the brilliance of the nearby planets. Now, exactly 400 years later, a pair of astronomers at The Johns Hopkins University is using NASA’s three Great Observatories to unravel still-mysterious aspects of the remains of this supernova, the last such object seen to explode in our Milky Way galaxy.
When this bright object – now called "Kepler’s supernova remnant" – appeared alongside Jupiter, Mars, and Saturn on that long-ago October evening, observers had only their naked eyes with which to study it because the telescope would not be invented for another four years. Johns Hopkins University astronomers Ravi Sankrit and William P. Blair, however, have the combined abilities of the Spitzer Space Telescope, the Hubble Space Telescope, and the Chandra X-ray Observatory at their disposal, and are using them to analyze the continuously expanding supernova remnant’s appearance three ways: in infrared radiation, visible light and X-rays.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
